HORIZONTAL DIFFUSION IN TIDAL MODELS AND SCALING CRITEREA FOR THERMAL-HYDRAULIC MODEL TESTS

Gerd Flugge

Abstract


Near Brokdorf at the lower Elbe river (West Germany) a nuclear power plant is projected. The electric energy output shall be 1300 MWe; therefore the waste heat output will be about 2600 MWe. The maximum allowed temperature rise in the condenser amounts to 10 K. Accordingly the cooling water discharge is about 61 m /s in case of the provided once through cooling. For the purpose of the mixing and spreading of the discharged cooling water by mean tidal conditions and storm-tide conditions model tests have been carried out at the Franzius-Institut of the Technical University of Hannover.
